Method Detail

serialize

public java.lang.Long serialize(java.lang.Object input)

Description copied from interface: Coercing

Called to convert a Java object result of a DataFetcher to a valid runtime value for the scalar type.

Note : Throw CoercingSerializeException if there is fundamental problem during serialisation, don't return null to indicate failure.

Note : You should not allow RuntimeExceptions to come out of your serialize method, but rather catch them and fire them as CoercingSerializeException instead as per the method contract.

Specified by:

serialize in interface Coercing<java.lang.Long,java.lang.Long>

Parameters:

input - is never null

Returns:

a serialized value which may be null.

parseValue

public java.lang.Long parseValue(java.lang.Object input)

Description copied from interface: Coercing

Called to resolve an input from a query variable into a Java object acceptable for the scalar type.

Note : You should not allow RuntimeExceptions to come out of your parseValue method, but rather catch them and fire them as CoercingParseValueException instead as per the method contract.

Specified by:

parseValue in interface Coercing<java.lang.Long,java.lang.Long>

Parameters:

input - is never null

Returns:

a parsed value which is never null

parseLiteral

public java.lang.Long parseLiteral(java.lang.Object input)

Description copied from interface: Coercing

Called during query validation to convert a query input AST node into a Java object acceptable for the scalar type. The input object will be an instance of Value.

Note : You should not allow RuntimeExceptions to come out of your parseLiteral method, but rather catch them and fire them as CoercingParseLiteralException instead as per the method contract.

Specified by:

parseLiteral in interface Coercing<java.lang.Long,java.lang.Long>

Parameters:

input - is never null

Returns:

a parsed value which is never null
